2 Claims.

This invention relates to clips and has more particular reference to animproved clip adapted to be mounted on any convenient flat surface, suchas a table top, desk or the like.

A principal object of the invention is the pro* vision of a device forfacilitating cleaning and sharpening of erasers, or the like.

Another important object of the invention is the provision of a clipwhich is adapted to be removably secured to a tab-le or desk top andwhich also has an abrasive surface formed in the upper portion thereof.

Another important ob-ject of the invention is the provision of a cliphaving one surface roughened to provide means for cleaning andrevitalizing an eraser, or the like.

Another important object of the invention is the provision of a metalclip having an abrasive surface formed in one surface thereof, which isadapted to be easily mounted or otherwise secured to a table top or desksuch as a typewriter desk or the like for cleaning and sharpening anytype of eraser before applying the eraser to the work.

Numerous other objects and advantages of the invention will be apparentas it is better under- Stood from the following description, which, whentaken in connection with the accompanying drawing, discloses a preferredembodiment thereof.

In the drawing:

Figure l is a top plan view of my improved clip showing one form ofabrasive surface formed thereon;

Fig. 2 is a side elevational view of my improved clip ready forinstallations;

Fig. 3 is a side elevational view of my improved clip mounted on a tabletop; and

Fig. 4 is an enlarged cross-sectional view of my improved clip, takensubstantially on line 4 4 of Fig. 1.

Referring more particularly to the drawing, reference numeral IIindicates in general a clip member. The clip II is preferably made of af relatively thin strip of metallic spring material although it will beunderstood that any desired or suitable material may be used, andcomprises a laterally extending flat surface I2 and a second surface I3which is bent or formed at I4 to form a bifurcated member.

The flat surface I2 is scored as at I5, in any suitable manner, to forman abrasive surface. The surface I5 is then hardened in the usual mannerso as to present an abrasive surface which is durable and long-lived.

(Cl. 1Z0-8) The surface I3 is bent at I6 and Il to form a spring tensionmember which will hold the clip II rmly against the upper surface of atable I8 as illustrated in Fig. 3.

It is to be understood that while the preferred form of an abrasivesurface I5 is made by scoring the portion I2 any other suitable abrasivesurface may be provided. The portion I2 may be cut away so that anabrasive material, such as carborundum or any like material may beinserted therein or a strip of abrasive material may be positioned uponthe upper surface thereof and securely held by any suitable or desiredfastening means.

Further, while the clip II is illustrated as being positioned upon atable top I8 (Fig. 3), the clip II may also be used upon a desk havinga. glass top as well as upon a shelf or desk insert.

It has been found that after an eraser has been used a number of times,a certain amount of dirt will collect upon the rubbing surface and causea smudge when used thereafter. It has also been found that after aneraser has been used for a certain length of time, it will lose acertain amount of its life and become hard and unusable, and the erasermust be discarded. Furthermore, when an eraser is used but seldom, therubber will harden and the eraser become unusable. Such erasers whenrubbed across the abrasive surface I5 and the accumulated dirt removedfrom the rubbing surface of the eraser, present a fresh surface whichwill facilitate erasing. Also by rubbing the eraser over the abrasivesurface I5 it will tend to keep the rubber alive and prevent the erasersfrom getting hard and losing their rubbing qualities, and furthermore,such rubbing will revitalize the eraser which has become hard andunusable thereby prolonging its life and period of use.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.

I claim:

1. An article of manufacture, comprising a unitary spring clip memberhaving a flat portion adapted to be disposed upon the upper surface of adesk top, or the like, abrasive means formed on the upper surface ofsaid flat portion to facilitate cleaning of an eraser thereon, and alower porarea formed on the upper surface of said flat portion toprovide means for cleaning an eraser, said flat portion being bent backupon itself to form a lower portion integral therewith and disposed inspaced relationship thereto to provide a tensioning member adapted tofrictionally engage the under surface of said desk top to secure theclip member in proper eraser cleaning position thereon with said flatportion in planar engagement with the upper surface of said desk top. lo
